桥梁施工检测方法

在桥梁施工过程中经常需要对各施下部件的位置进行检测，本文结合海瑞大桥安全性检测工作，讨论了桥梁施工检测过程中控制网布设、GPS-RTK桥桩放样和承台中心位置及高程测量、墩台中心及台项高程的全站仪测量方法，为GPS-RTK结合全站仪进行桥梁检测提供了有益的案例。

Examining Surveying Method in Bridge Construction

During bridge construction, it always needs to check the position and elevation of the bridge's components. Combined with the security survey of Hai-rui Bridge, this paper discusses the establishment of the bridge control network, the GPS RTK surveying of the central position and elevation of bridge stake's bedrock, and the total station surveying of bridge frusta. The method in this paper provides helpful case for the bridge examining surveying with GPS RTK and total station.
